APPARATUS FOR GARBURETI NG AIR.

Specification of Letters Patent.

Patented Sept. 4t, limit.

Application filed March 4, 1916. Serial No. 82,051.

To all whom it may concern;

Be it known that 1, CHARLES N. GRAY, a citizen of the United States, residing at Yankton, in the county of Yankton and State of South Dakota, have invented a new and useful Improvement in Apparatus for Carbureting Air, of which the following is a specification.

An object of this invention is the production of apparatus for carbureting air and more particularly relates to means for evaporating oil or other hydrocarbon in a highly efficient and effective manner to furnish a highly combustible constituent in the form of mixed air and liquid in a volatilized form for heating, illuminating, power and other purposes.

Further objects are to decrease the hazard of explosion by regulating the flow of gasolene or other liquid hydrocarbon into the carbureter and causing the parts of the apparatus to deliver a constant supply of rich mixture evenly, to enable the isolation of the supply tank containing the oil and the car bureting apparatus a long distance from the dwelling or structure where the mixture is used and to eifeotively pump the gasolene at such distance.

To these ends my invention comprises the features of construction and combination of parts, which will be hereinafter more particularly described and pointed out in the claim.

In the accompanying drawing forming part of this specification, Figure 1 is a side elevation of my improved apparatus for carbureting air; Fig. 2 is a plan of my improved carbureter forming part of said apparatus, a portion of said carbureter being broken away to more clearly disclose the interior construction; Fig. 3 is a section taken upon the line XX of Fig. 2; Fig. 4 is a section of a detail of my improved pump employed in said apparatus, and Fig. 5 is a section of a detail of one of the pipes leading to the carbureter.

In the drawing, A is the usual air blower, which is operated by the usual weight motor B (not shown), situated near where the mixture developed by my improved apparatus 'is to be used. C is a pump, the piston 2 in the cylinder 3 of which is reciprocated by the use of the weight motor B during its operation. D indicates the main gasolene or other hydrocarbon supply tank which is filled through the supply pipe 4:. Situated near and above the supply tank is a carbureter F, which is supplied with air from the blower A through the air supply pipe 5. The lower end of the cylinder 3 of the force pump C is connected with the carbureter F by aga'solene supply pipe 6, a branch 7 leadlng from the main gasolene supply tank D being connected with said pipe, so that when the piston 2 is being raised, gasolene flows from the supply tank D into chamber G and is ultimately forced upwardly into the top of the carbureter by the downward stroke of piston 2. A small reservoir chamber G is interposed in the pipe 6 immediately below the junction of the branch 7 into which the gasolene flows, thereby maintaining a supply of gasolene for the air from the downward stroke of piston 2 to discharge into the carbureter. A check valve 8 is interposed in the branch 7, so that gasolene or air cannot be forced through the branch into the supply tank D. During the upward suction stroke of the piston 2, air in pipe 6 is drawn back. By this means gasolene in tank D runs freely through check valve 8 until it has filled chamber G and pipe 6 up to the level of gasolene in tank D. An auxiliary check valve .9 keeps the pump from drawing gasolene up thereinto. Another check valve 11 interposed in the pipe 6 below the reservoir G locks and prevents the return of gasolene or mixture from the carbureter into the reservoir. The supply tank D, carbureter F and reservoir G with said connected piping is preferably embedded in the ground at a distance from the blower and pump, so as to reduce the hazard from explosion or accident.

My improved carbureter is in the form of a casing 15 having a plurality of partition walls 16 projecting alternately inwardly from the end walls 17 and 18 of said casing, thereby forming a channel running longitudinally of the casing backwardly and forwardly. The walls are evenly spaced apart and from the side walls of the casing, thereby forming a channel H of even width throughout its length. Hung from the top 19 of the casing at frequent intervals throughout the length of said channel are a number of flexible baflie walls 20 made out of absorbent material, such as cheese cloth, which depend into the gasolene which is fed into the channel formed by the weirs and casing. The gasolene in the carbureter is maintained at even height, an overflow duct 21 being connected with the channela short distance above the floor of the casing and emptying into the supply pipe i from whence it returns into the supply tank D. The lower ends of the bafiles dip into the gasolenein the carbureter and by capillary attraction become thoroughly moistened. The air pipe 5 from the blower enters the carbureter through the top 19 at one end of the channel containing the gasolene and passes backwardly and forwardly over the gasolene and below the baffles to the Outlet end of the channel from whence the vapor emerges through the gas supply pipe 22 leading to the locations where the mixture is to be em 'iloyed for service. The lower ends of the baffle walls 20 are formed with upwardly projecting'openings 23 in that portion of the battle which dips into and extends slightly above the surface of the gasolene. These slits or openings in the balfle walls allow the passage of air and the air or vapor keeps the baflies in constant motion, thereby causing more thorough vaporization of the gasolene and mixture of the air with the gasolene. By the use of these flexible flapping bafile walls which are hung by their upper ends from the top of the casing and constructed as described, more perfect carbureting action occurs. Asmany baflle walls may be used as desired, it'being obvious that the more ballie walls employed, the greater the vaporization of the gasolene.

During the operation of my improved apparatus, gasolene is forced by the pump from reservoir chamber G into the top of the carbureter at that end of the channel in which air is forced by the blower.

A steady supply of rich mixture from the carbureter is produced, the reciprocations of the piston in the pump being thoroughly .ply pipes 22. During this operation chamber G acts as a seal to prevent airfrom forc ing through into carbureter F with each stroke of the piston in the pump. The pump G has its piston Qprovided with oil grooves 25, which are adapted to be filled with heavy oil through a channel 26 and branches 27 leading therefrom.

In accordance with the patent statutes, I have described the principles of operation of my invention, together with the apparatus which I now consider to represent the best embodiment thereof, but I desire to have it understood that the construction shown is only illustrative, and that the in vention can be carried out by other means and applied to uses other than those above set forth within the scope of the following claim. a

Having described my invention, what I claim as new and desire to protect by Letters Patent is: I

A carbureter comprising a closed tank having a gasolene feed and an air inlet, a gas outlet, and a plurality of spaced absorbent flexible baflie sheets attached along their upper edges to the top of the tank and loosely disposed transverselyof the flow of gasolene and air, each of said sheets being provided with a V-slot centrally thereof, said slot extending from the lower edge of the sheet to a point approximately midway of its vertical length.

In testimony whereof, I have signed my name tothis specification.

CHARLES N. GRAY. I
